ONE OF THE MOST SIGNIFICANT SEVERE WEATHER OUTBREAKS OF THE
SUMMER OCCURRED ON SUNDAY AUGUST 2 WHEN SEVERAL ROUNDS OF VIOLENT
THUNDERSTORMS CROSSED SOUTHERN ONTARIO. THE TRIGGER WAS A COMBINATION
OF VERY WARM AND HUMID CONDITIONS COUPLED WITH STRONG UPPER LEVEL
WINDS AHEAD OF A COLD FRONT. THE FIRST ROUND OF STORMS RAPIDLY BECAME
ORGANIZED IN THE AFTERNOON AND CAME ASHORE FROM LAKE HURON AND
ACCELERATED SOUTHEASTWARDS TOWARDS LAKE ONTARIO, CAUSING CONSIDERABLE
SWATHS OF STRAIGHT-LINE WIND DAMAGE. THERE MAY HAVE BEEN A BRIEF
TORNADO OR TWO ASSOCIATED WITH THIS FIRST BOUT OF SEVERE STORMS, BUT
THERE WAS NO SERIOUS DAMAGE OR CONFIRMED REPORTS.

THE SECOND MAIN ESPISODE OF STORMS HIT PRIMARILY IN THE EVENING,
AFFECTING MANY OF THE SAME AREA AS THE EARLIER STORMS BUT WITH THE
ADDITION OF ALL OF SOUTHWESTERN ONTARIO. SOME TORNADIC WINDS MAY
HAVE BEEN ASSOCIATED WITH THE EVENING STORMS AS WELL.

MOST OF THE SEVERE WEATHER REPORTS WERE FROM STRAIGHT LINE WINDS,
WITH MANY REPORTS OF HAIL RANGING FROM DIME TO GOLF BALL SIZE. MANY
THOUSANDS OF HYDRO CUSTOMERS WERE WITHOUT POWER DUE TO SPORADIC
SWATHS OF DOWNED TREES ACROSS THE REGION. ONE POTENTIAL TORNADO
REPORT NEAR TEVIOTDALE (SOUTH OF MOUNT FOREST) AROUND 9 P.M. EDT IS
BEING INVESTIGATED BY AN ENVIRONMENT CANADA SURVEY TEAM TODAY. THIS
BULLETIN WILL BE UPDATED AS FURTHER INFORMATION BECOMES AVAILABLE ON
THIS SURVEY AS WELL AS ANY OTHER SIGNIFICANT UPDATED REPORTS.

THE FOLLOWING IS A SUMMARY OF WEATHER EVENT INFORMATION RECEIVED BY
ENVIRONMENT CANADA.

CONFIRMED EF-2 TORNADO IN TEVIOTDALE WITH WINDS OF 180 TO 220
KILOMETRES PER HOUR. THE DAMAGE PATH IS ROUGHLY 7 KILOMETRES LONG BY
200 METRES WIDE.
